ELECTRIC HAIR SINGEING DEVICE Filed NOV. 5, 1961 INVENTOR Grady L.Johnson ATTORNEY 3,093,724 ELECTRIC HAIR SINGEENG DEVICE Grady L.Johnson, 619 W. Howard Ave., Decatur, Ga. Filed Nov. 3, 1961, Ser. No.149,948 2 Claims. (Cl. 219-29) The invention relates to electric hairsingeing devices adapted to shave by singeing the hairs of the beard, anobject being to provide such a device in the form of a comb or head ofnon-electric conducting fireproof material combined with a wire blade ofelectric conducting material, in which said comb has two sets of teeth,said sets being spaced apart from each other by a longitudinal slot; theteeth of one set being shorter than those of the other set; the longerteeth having their free end portions projecting beyond the free ends ofthe shorter teeth; said teeth being tapered and of gradually increasingthickness towards their root ends, said blade being connected with asource of electric current to heat it to a hair singeing temperature,said blade being adjustable upwardly and downwardly within said slot tovary its singeing effect.

The invention consists in the novel construction and combinations ofparts hereinafter set forth in the claims.

In the accompanying drawings:

FIGURE 1 is a side view of the invention, showing the Wire bladeadjusted upwardly in the slot of the comb from its lowermost position.

FIGURE 2 is a detail side view of the wire blade.

FIGURE 3 is a perspective view of the invention, partly broken away,showing the wire blade in its lowermost position, the securing nutsbeing shown detached from the blade.

FIGURE 4 is a section on the line 4-4, FIGURE 1.

Referring to the drawings, the comb or head is shown as provided withtwo sets of tapered teeth, said sets designated respectively 1 and 2being spaced apart from each other by a longitudinal slot 3 of saidhead. The numeral 4 designates a longitudinal wire blade located withinsaid slot, the teeth of each set being of gradually increasing thicknesstowards their root ends, due to their said taper, said comb or headbeing of electric non-conducting fireproof material, said blade being ofelectric conducting material and adapted to be connected with a sourceof electric current and to be heated thereby to hair singeingtemperature, said blade being adjustable upwardly and downwardly withinsaid slot to vary its singeing effect.

United States Patent The teeth of one of said sets are shorter thanthose of the other set, the longer teeth having their free end portionsprojecting beyond the free ends of the shorter teeth, said blade beingadjustable downwardly within said slot to expose it below the shorterteeth of said other set for maximum singeing eifect.

The terminals of the positive and negative conductor wires 5 and 6 areconnected with end plates 7 and 8 of electric conducting material withwhich said blade 4 is in electrical contact at all times.

The wire blade 4- has its end portions threaded at 4', nuts 8' beingscrewed upon said end portions into tight engagement with said endplates to secure the wire blade in position as adjusted in said slot,said blade 4 and said end plates 7 forming part of the electric circuitfor heating said wire blade 4.

The electric current may be regulated by a suitable rheostat, not shown.

The right is reserved to modifications coming within the scope of theclaims.

I claim:

1. An electric hair singeing device comprising an elongated headprovided with two sets of tapered comb teeth, said sets being spacedapart from each other by a longitudinal slot of said head, and alongitudinal wire blade located within said slot, the teeth of each setbeing of gradually increasing thickness towards their root ends due totheir taper, said head being of electric non-conducting fireproofmaterial, said blade being of electric conducting material and adaptedto be connected to a source of electric current and to have itstemperature raised to hair singeing temperature, said blade beingadjustable upwardly and downwardly within said slot to vary its singeingeffect.

2. An electric hair singeing device as defined in claim 1, in which theteeth of one set are shorter than the teeth of the other set, the teethof the longer set having their free end portions projecting beyond thefree ends of the shorter teeth, said blade being adjustable downwardlywithin said slot to expose it below the shorter teeth of said other setfor maximum hair singeing effect.
